Serial No. 531,383.

To all whom 'it may concern:

Be it known that I, EUGENE NELSON I'IEARD, a citizen of the United States, residin at Oakland, in the county of Alameda and Sitate of California, have invented certain new and useful Improvements in Advertising-Signs, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to changeable sign exhibiting devices, and the principal object of the same is to provide an exhibitor of the type specified in which a plurality of signs are automatically and intermittently exhibited in an attractive manner.

In carrying out the objects of the invention generally stated above it is contemplated providing a casing in which a plurality of rollers are rotatably mounted, each roller having an endless connection with a rotatable slat at the front of the casing, said endless connections having advertisements or the like thereon, means being provided whereby the slats are intermittently rotated to exhibit a portion of the endless connector that passes over them, said means concealing the slats while the latter are being rotated.

In the practical application of the invention it will be understood, of course, that the essential features thereof are necessarily susceptible of changes in details and structural arrangements, one preferred and practical embodiment of the invention being shown in the accompanying drawings, wherein Figure 1 is a View in front elevation of the improved sign exhibitor. Fig. 2 is a vertical sectional view taken on the line XX, Fig. 1. Fig. 3 is a fragmentary detail view of one of the operating chains and its adjuncts for operating the exhibitor. Fig. 4 is an enlarged detail fragmentary view showing the manner of intermittently rotating the sign supporting slats. Fig. 5 is a rear elevation of a shield which is equipped with means for rotating the slats. Fig. 6 is a fragmentary top plan view thereof. Fig. 7 is a similar view of one end of one of the slats.

Referring to the accompanying drawings by numerals, 1 designates a substantially rectangular casing that has a rear doorway 2 through which access may be had to the interior of the casing, a door 3 being provided for said doorway. At the front the casing 1 is provided with a frame 1 which supports the glass or other transparent front covering 5. To each side of the doorway 2 a vertical strip 6 is provided that has regularly spaced apart vertically arranged downwardly inclined bearing slots 7. And to each side of the front covering 5' and concealed by the frame 4: thereof, a side strip 8 is provided, said strips 8 having slots 9 corresponding in number to the slot 7 of strips 6 but arranged in a slightly lower plane. roller 10 is provided for each pair of oppositely disposed slots 7 of the strips 6, and a slat 11 having end shafts 12 is rotatably supported by each pair of oppositely disposed slots 9 of the supporting strips 8. This arrangement of slats and rollers disposes the same in pairs, and each pair is connected by a wide endless band 13 upon the outer surface of which advertising matter is placed. Each end shaft 12 of the slats is provided with a tripping arm 14: that is slightly spaced from and projects at right angles to the slats.

At the top of the front of the casing, and concealed by the frame 4 a horizontal shaft 15 is rotatably mounted, saidshaft having a sprocket wheel 16 adjacent each end. An idler guide pulley 17 is mounted below each sprocket 16 and between the same and said frame A. At the bottom of said casing, a horizontal shaft 18 is rotatably mounted, said shaft having end sprockets 19 above which, and toward the interior of the casing, an idler guide pulley 20 is provided for each sprocket 19. A sprocket chain 21 connects each pair of sprocket wheels 16 and 19, the flights of said chains being retained in vertical positions by the upper outer guide pulley 17 and the lower inner guide pulley 20. A conveyer pin 22 projects through and beyond the sides of one of the links of each chain 21.

A vertically arranged guiding groove 23 is arranged on each side of the casing 1 adjacent the front thereof, said grooves extending above and below the top and bottom of the front covering 5.

A fiat shield 24 extends transversely across the front of the casing 1 and has its ends passed between the flights of sprocket chains 21 and slidably mounted in the guiding grooves 23. The shield may be of sheet metal and adjacent each lower corner of its inner surface is provided with a pair of spaced apart outwardly projecting pins 25 between which the inner flights of the chains 21 pass. The upper corner portions of the and when said pins 22 contact therewith, the

" when said slats are 7 as',will presently are also provided-with a spring arm that outer surface of the with pins 26 arranged similar to the a 25 of the inner surface of the shield and between which the outer flights of chains. 21- pass. Said pins 25 and of movement of the pins 22 of said chains shield 24 is moved vertically of the casing 1', as will be more fully explained. The shield 24 is provided with upper and lower inwardly projecting flanges 27-28, respectively which terminate adjacent the slats 1-1 in an edgewise position. Said flanges terminate adjacent each end of thev shield'24 so that" clearance space 'is provided for the chains 21, as is shown more clearly in Fig; 5 of the accompanying drawings. 'Adjacent each upper corner of the inner surface, of the shield-24, and beneath the upper flange 27 thereof, an outwardly projecting rigid cam 29 is provided, said cams being adapted to rotate the slats 11, be explained. Said cams prevents further rotation of a slat afterthe cam lia s left't he slat. A rocker shaft 31 is rotatably mounted, on the inner face of the 5 Shield 24below the cams 29, said shaft extending across the transverse openings 32 adjacent the ends of-said shield. A pair of cams 33 are fast on said shaft, one beiiig in alin ement with each opening 32' and adapted to be projected therethrough when 7 42 are provided whose free ends bear upon the ends of shield 24, when the latter is at saidshaft'is rockedm one direction Said cams 33 are located so that they will actuate slats. 11. On its the tripping arms 14 of the and adjacent one end thereof, the

outer face,

shield 24 is provided with a pair of spaced;

'guideleyes' 34 in which a vertically arrangedftrlpping rod '35 is slidable. Said rod carries an abutment collar 36- for con- A tact with'the lower eye 34' tical movement of the rod to limit the verdirection. Aheaded lug 37 projects laterallyfroinv said rod 35- and has a link 38 slidable thereon, said link proj ecting through 4 a slot; 39- in. the shield 24' and having. one; end" rigidly fastenedlto theiro'cker'shaft 31. Abutm'ents'40-'41 are provided at the upper for saidand lower portion of the casing 1 rod 35' to'llilnitits vertical movement.

Attheupper portion of casing 1, springs theupper portion of thecasing, and exert a pressure thereon to cause the'shieldto bind withinitsl guiding grooves 23 so that; said shield will-,be'f yi'eldably held-'at'the' upper' portionvof the casin casing 1, said, motor havinglal belt conneck shaft 18.

26 are in the path a in a downward motor 43 is mounted on the base o fthe,

The shield 24 is of a width equal to the Width of three. of the slats 11, and in operation, assuming the shield to be at the upper end; of the casing and held there by the pressure of springs 42, it will be seen that the chains 21 traveling over the upper sprockets 16 their pins 22 will engage pins 25 of shield 24. When the shield is at its uppermost position, tripping rod 35 has contacted with abutment 40, which moves rod 35 down- ;ward, and through link connection 38 with shaft 31', said shaft is rocked to projectcams outward. Pins 22 and. 25 being in en gagement, shield 24 is moved downward with chains. 21 causing cams 33 to contact gwith tripping. arms 14 which rocks shafts 12 iandturns slats 1 1 to a position where they iare in the path of movement of cams 29 so fthat said cams'29 will: rock said slats-to a gposition parallel with chains 21. After the ifirst slat has been turned by cams 29 and iwhilesaid cams are startingto turn thenext islat, springs 30 are incontact withthe previgously turned slat and prevent it turning be- 5 yond a position parallel with said chains 21. !This intermittent rotation of theslats is conjtinueduntil the lowermost position of shield 24is reached, whereupon rod'35 contacts with iabutment 41 and is raised relative to shield }24, and through its link connection with irocker shaft 31,rocks the latter so the cams 33 are drawn into openings 32 so that they Swill not contact with the arms 14' on the upiward movement of shield 24. Simultane- ;ously with the withdrawal of cams 33, the outward bend of chains 21 necessaryto pass jzover sprockets 19, causes said chainsto withdraw their pins 22 from engagementwith {pins 25,- thereby releasing said shield. After gthe chains 21 have passed over sprockets 19, itheir pins 22 engage pins 26 of shield24, icausing said shiel'd to travel upward with said chains. The upward movement, of gshield 24 performs no operation on theslat-s 511' for the reason that cams 33 are withdrawn so that they cannot contact witharms {14, and cams 29 cannot contact with slats 11 for the reason that said slats are in edge- ;wise relation and parallel with the chains 521. When the uppermost position of shield .524 is reached, rod 35 automatically shifts the positions ofcams33-by contact with abut- ;ment 40, and pins 22 and 26 are disengaged :bythe outward bendof; the chainsnecessary gto pass over sprockets 16,. after which the downward movement of the shield is efg'fected as hasbeen described.

i It will be seen from the foregoing that ithe improved exhibitor provides means iwhereby' the turning of the slats is perifprmed intermittently and automatically,

one slat being partially rotated-by the cams smaller pulley47 that has; belt eonn aioa'iswiur a pulley '49 on .33'and' the rotation of said slat completed by the cams 29, the previously turned slat 1' being held and steadied by springs 30, so

that it will stay in the proper position to effectively display the advertisement, or part of the advertisement, contained on its endless connector 13. The longitudinal edges 11 of the slats are preferably beveled so that the interior of the casing 1 cannot be viewed through the front of the casing when the slats are in their exhibiting positions. And the frame a is so constructed that it conceals from view the operating mechanism of the exhibitor. It will also be understood that the cams 29-33 are so arranged on the shield 24 that they will have finished their slat turning operations before the shield has moved from position in front of the slats being turned.
